12.1.4 - Cavitation protection
To ensure the durability of pumps fitted within the integrated
(1)
hydraulic modules, the control algorithm for units includes
protection against cavitation. It is therefore necessary to ensure
a minimum pressure at the pump inlet both when shut down and
during operation. A pressure below the predefined threshold will
prevent unit start-up or will cause an alarm and shutdown. Before
complete shutdown following an alarm, the user interface will give
an advance warning that this threshold has been exceeded.
To obtain an adequate pressure, it is recommended:
■ That the hydraulic circuit is pressurized between 100 kpa
(1 bar) and 400 kpa (4 bar) maximum at the pump inlet,
■ That the hydraulic circuit is cleaned when filled with water or
when modified,
(1)
■ That the screen filter is cleaned regularly.
